The nominees in the category are Iggy Azalea, Beyoncé, Luke Bryan, Eminem, Imagine Dragons, John Legend, Lorde, One Direction, Katy Perry and Pharrell Williams. The 10 nominees will be narrowed to five based on the votes received through Nov. 13 and the winner will be determined by the total votes received throughout the entire voting period.
Five songs are up for single of the year this year, up from three in the previous year. The singles are "Fancy," by Azalea featuring Charli XCX; "All of Me," by John Legend; "Rude," by MAGIC!; "Dark Horse," by Katy Perry featuring Juicy J and "Happy" by Pharrell Williams.
The AMAs are voted on by fans, with the winners determined by votes cast online and via Twitter.
Nominations are based on key fan interactions reflected in Billboard Magazine and on Billboard.com, including album and digital singles sales, radio airplay, streaming and social activity, according to the awards.
The 42 annual American Music Awards will be broadcast live from the NOKIA Theatre L.A. on Sunday, November 23rd on ABC. Pre-show live coverage will stream online for fans worldwide starting at 5:00 p.m. ET on Yahoo.com.
